Enter the total resistance (ohms) and the total length (m) into the Calculator. The calculator will evaluate the Resistance Per Meter. 

Resistance Per Meter Formula

RPL = R / L


  • RPL is the Resistance Per Meter (ohms/m)
  • R is the total resistance (ohms)
  • L is the total length (m)

To calculate Resistance Per Meter, divide the total resistance by the total length.

How to Calculate Resistance Per Meter?

The following steps outline how to calculate the Resistance Per Meter.

  1. First, determine the total resistance (ohms). 
  2. Next, determine the total length (m). 
  3. Next, gather the formula from above = RPL = R / L.
  4. Finally, calculate the Resistance Per Meter.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total resistance (ohms) = 30

total length (m) = 230
